QA/G-4 provides non-mandatory guidance on developing Data Quality Objectives (DQOs) using a systematic planning process based on the graded approach. The guidance presents a step-by-step description of the DQO process. The Aug 2000 version supercedes the Sept 1994 version.

QA/G-5 provides guidance on developing Quality Assurance Project Plans (QAPPs) that will meet EPA expectations and requirements. This document provides a linkage between the DQO process and the QAPP. It contains tips, advice, and case studies to help users develop improved QAPPs.

QA/G-4HW provides guidance on applying the Data Quality Objectives (DQO) process to hazardous waste site investigations. The guidance presents a step-by-step description of the DQO process and its application to sampling designs for environmental remediation and waste management activities.

QA/G-5i will provide guidance on data quality indicators (DQIs), including the PARRC parameters (i.e., precision, accuracy, reproducibility, representativeness, and comparability) and how they fit into the implementation of the DQO process. The guidance discusses the role of DQIs in sampling and analytical measurements.

Peer review of this document is complete. A final version has been drafted but has not been released as yet. Target date: Unknown.

QA/G-5M adapts the current EPA QA/G-5 for modeling projects emphasizing applicable QA Project Plan elements for example, assessment of acquired data and software/hardware configuration testing. Issues such as regulatory task focused systematic planning and the use of the graded approach to match model complexity to the need for evaluation and testing are also addressed.

QA/G-8 provides non-mandatory guidance to assist users in verifying and validating environmental data. The guidance discusses alternative approaches to data validation, including examples of statistics-based validation techniques, and options for verifying that the validated data satisfy relevant claims about their authenticity and quality.

Region 10 Quality Management Plan

This document defines and describes the Quality Management (QM), Quality Assurance (QA), and Quality Control (QC) policies and responsibilities required by Region 10, in concurrence with the Agency's mandated QM program.

This document can be considered the technical aspect of G-9R. The document is designed as a "tool-box" of useful techniques in assessing the quality of data. The overall structure of the document will enable the analyst to investigate many different problems using a systematic methodology. For more information and resources, see Tools - Data Quality Assessment.
